MASM32编程通过WMI获取Windows计划任务
上回MASM32编程使用了Windows系统提供的API函数：NetScheduleJobEnum（）来枚举Windows计划任务（详见 MASM32编程枚举Windows计划任务，http://blog.csdn.net/Purpleendurer/archive/2009/11/05/4774148.aspx），这次通过WMI来实现。
需要注意的是：不管是通过WMI，还是使用API函数NetScheduleJobEnum()，都只能枚举使用Win32_ScheduledJob类别或At.exe实用程序创建的计划任务。
所以 pe_xscan 在扫描计划任务时使用的是另外一种方法:-D
完整的代码如下：
